CA glue was in veterinary use for mending bone, hide, and tortoise shell by the early 1970s or before. Harry Coover said in 1966 that a CA spray was used in the Vietnam war[3] to retard bleeding in wounded soldiers until they could be brought to a hospital. Butyl cyanoacrylate[4] has been used medically since the 1970s. In the US, due to its potential to irritate the skin, the U.S. Food and Drug Administration[5] did not approve its use as a medical adhesive until 1998 with Dermabond[6].[11][7] Research has demonstrated the use of cyanoacrylate in wound closure as being safer and more functional than traditional suturing[8] (stitches).[12][9] The adhesive has demonstrated superior performance in the time required to close a wound, incidence of infection (suture canals through the skin’s epidermal, dermal, and subcutaneous fat layers introduce extra routes of contamination),[12][9] and final cosmetic appearance.
